Daniel Defense Rifle Length Gas Tube

Product Description

The Daniel Defense Rifle Length Gas Tube is a genuine replacement gas tube designed for AR-15 upper receivers configured with rifle-length gas systems.

This gas tube transfers propellant gas from the gas port to the bolt carrier group, cycling the action. It’s built for standard AR-15 rifles running a rifle-length gas system, the longest of the common gas system configurations.

Whether you’re replacing a damaged tube or building a custom upper, this component maintains the precise gas regulation that rifle-length systems are known for.

Daniel Defense Gas Tube Fit and Gas System Length

Rifle-length gas systems use the longest gas tube, spanning approximately 15 inches from gas block to upper receiver. This configuration is common on 20-inch barrels and some 18-inch builds, where the gas port sits farther from the chamber.

The longer dwell time in rifle-length systems often results in softer recoil impulse compared to mid-length or carbine configurations. That makes this gas tube the right choice when building or repairing uppers designed around full-length rifle gas ports.

Not compatible with mid-length or carbine gas systems. Match the gas tube length to the gas block position on your barrel.

What to Know Before Ordering a Daniel Defense Gas Tube

Gas tubes are consumable parts. They can crack, bend, or corrode after extended use or exposure to corrosive ammunition residue. Inspect yours during routine cleaning, especially around the bend where stress concentrates.

Installation requires a gas tube roll pin and basic armorer’s tools. The roll pin secures the tube inside the upper receiver’s gas key channel. Take care during installation to avoid damaging the pin or enlarging the gas key holes.

Frequently Asked Questions

Q: Will this Daniel Defense gas tube fit a mid-length gas system?

A: No, this rifle-length gas tube will not fit a mid-length system. Rifle-length tubes are significantly longer than mid-length tubes and must match the gas port position on your barrel. Use a mid-length gas tube for mid-length gas blocks and a rifle-length tube for rifle-length configurations.

Q: What is the difference between rifle length and carbine length gas tubes?

A: Rifle-length gas tubes are longer and designed for gas ports positioned farther from the chamber, typically on 18-inch to 20-inch barrels. Carbine-length tubes are shorter and pair with gas ports closer to the chamber, common on 14.5-inch to 16-inch barrels. The two are not interchangeable.

Q: Is the Daniel Defense gas tube roll pin stainless steel?

A: Yes, the gas tube roll pin is stainless steel according to the product features. Stainless roll pins resist corrosion better than carbon steel pins, especially in humid climates or when exposed to moisture.

Q: Can I install this gas tube myself or do I need a gunsmith?

A: You can install this gas tube with basic armorer’s tools and attention to detail. The process involves aligning the tube in the upper receiver and driving the roll pin through the gas key. If you’re not confident working with small pins and tight tolerances, contact Western Sport at 817-393-4000 for gunsmithing assistance.

Q: How do I know if my gas tube needs replacement?

A: Replace your gas tube if you see visible cracks, especially near the bend, erosion around the gas port end, or permanent bending. Cycling problems can also indicate a damaged or obstructed gas tube. Inspect the tube during regular upper receiver maintenance.

Q: Does Daniel Defense offer a warranty on this gas tube?

A: Call 817-393-4000 to confirm current warranty terms. Warranty policies vary by component and purchase date, and Western Sport can help you verify coverage or address any product concerns.
